Tax Planning Under IRC § 1202 With Trusts and “Stacking” Strategies

Introduction to IRC § 1202 and the "stacking" strategy

IRC § 1202 provides a qualified small business stock (QSBS) gain exclusion that allows an individual, trust, or estate (any "taxpayer other than a corporation") to exclude a significant amount of capital gain on the sale of QSBS.^[1] For founders and early investors, it is often the largest single number in a high net worth estate plan.

For stock acquired after September 27, 2010 and held more than five years, 100 percent of the gain can be excluded, up to the greater of $10 million or ten times basis, per issuer and per taxpayer. For stock acquired after July 4, 2025, the dollar cap is $15 million and a partial exclusion begins at three years.^{[1, 2]} The cap applies to each taxpayer separately. Multiple taxpayers who hold QSBS in the same company can each claim their own exclusion on that company's stock, and nothing in Section 1202 combines or prorates the cap among a donor and the people or trusts that receive shares by gift.^{[1, 11]}

That gives rise to QSBS stacking: an estate planning technique that spreads stock ownership among several taxpayers, usually family members and non-grantor trusts, so that each owner is entitled to a separate exclusion when the company is sold.^[3] It belongs in any conversation about pre-sale and liquidity event planning, and it works best when that conversation happens years before a buyer appears.

Example: A founder holds QSBS worth $30 million, acquired in 2019. Selling alone, the founder can exclude $10 million. If the founder had earlier gifted shares to three non-grantor trusts, one for each child, and kept the rest, up to four separate $10 million exclusions may be available, enough to cover the entire $30 million.^[12] Each trust and the founder is a separate taxpayer, and each qualifies only if every Section 1202 requirement is met: original issuance, a domestic C corporation, the gross assets ceiling, an active qualified business, and the holding period.^[1]

Stacking can multiply tax-free gain dramatically, but it is not without risk. Too many similar trusts, or transfers made on the eve of a sale, invite challenge under the multiple trust rule of Section 643(f) and the assignment of income doctrine.^{[6, 13]} This guide surveys the authorities on QSBS trust planning: IRS guidance, case law, tax literature, CLE materials, and practitioner commentary, with a focus on grantor versus non-grantor trusts and the use of multiple trusts to maximize the exclusion. It is organized by source type, then brought home to Arizona.

Which rules apply to your shares: the July 4, 2025 dividing line

The One Big Beautiful Bill Act was signed on July 4, 2025, and Section 1202 now runs on two tracks. The date you acquired the stock decides which one you are on, and a gift does not move stock from one track to the other, because the donee is treated as having acquired the stock the same way and at the same time as the donor.^{[1, 2]} Our summaries of the Act's key takeaways and of the $15 million estate tax exemption cover the rest of the law.

Sources: 26 U.S.C. § 1202 as amended; Pub. L. No. 119-21; 26 U.S.C. § 2010(c); Rev. Proc. 2024-40; Rev. Proc. 2025-32.^{[1, 2, 16, 17, 18]} The gross assets ceiling is tested as of the date the stock was issued. The taxable part of a partially excluded gain is generally taxed at a maximum 28 percent rate rather than 20 percent.^[19]

Two practical consequences follow. First, the larger gift and estate tax exemption makes completed gifts of founder stock to non-grantor trusts easier to fit within a family's lifetime exemption. Second, a family may hold both legacy and post-enactment shares of the same company, and the statute coordinates the two caps so they cannot simply be added together.^[1]

Worked example: what QSBS stacking is worth

Illustration only. Assumes nominal basis, $10 million of gain in each holder's shares, stock held more than five years, every Section 1202 requirement met, and each trust respected as a separate taxpayer. The 23.8 percent rate combines the 20 percent maximum long-term capital gains rate and the 3.8 percent net investment income tax.^{[19, 20]} Each gift uses lifetime gift tax exemption measured by the stock's value on the gift date, not by the gain at sale, which is why early gifts are so efficient.^{[16, 3]} For post-enactment stock the same structure could protect up to $60 million.

The ten-times-basis cap changes the math for investors who paid real money for their shares. Because a donee takes the donor's basis, a founder who owns both low-basis common stock and high-basis preferred stock can often protect more gain by gifting low-basis shares to a trust, which will rely on the dollar cap, and keeping high-basis shares, which can use the ten-times cap. For that cap, basis is measured as of original issuance, without later additions.^{[1, 21, 14]}

IRS guidance and commentary on QSBS trust planning

Statutory framework

Section 1202 allows the exclusion to "a taxpayer other than a corporation," which includes trusts.^[1] Section 1202(h) then provides that certain transfers (by gift, at death, and from a partnership to a partner) are carryover transfers that do not disqualify QSBS. The transferee steps into the transferor's shoes for both original issuance and holding period.^[1] Section 1202(h) does not require the donor and donee to share a cap. If a shareholder gifts QSBS to a family member or to a trust that is a separate taxpayer, both the donor and the donee can claim a full exclusion on their respective shares.^{[1, 11]}

Grantor versus non-grantor trusts

The critical ruling is Rev. Rul. 85-13, which holds that when a trust is a grantor trust, the grantor is treated as the owner of its assets for income tax purposes and transactions between the grantor and the trust are ignored.^[4] It follows that moving QSBS into a grantor trust is not a transfer to a new taxpayer. A sale by the grantor trust is a sale by the grantor, and no additional cap is gained.^{[4, 11]} That covers every revocable living trust, most spousal lifetime access trusts (because the grantor's spouse is a beneficiary), and the many irrevocable trusts that are intentionally drafted as grantor trusts for estate tax reasons.^{[5, 22]}

Planners who want to stack therefore use non-grantor trusts. Private letter rulings are not precedent, but they illustrate the distinction. In PLR 201908006 the IRS analyzed an incomplete gift non-grantor ("ING") trust: a transfer that was incomplete for gift tax purposes, to a trust that no one was treated as owning for income tax purposes.^[23] The ruling does not address Section 1202, and it does not approve stacking. It shows that income tax ownership and gift tax completion are separate questions, and a stacking trust has to get the income tax answer right.

The multiple trust rule, and why you cannot get a ruling

The IRS has offered little formal guidance on how many trusts are too many.^[3] Section 643(f), enacted in 1984, treats two or more trusts as one if they have substantially the same grantor and substantially the same primary beneficiaries, and a principal purpose of the trusts is avoiding federal income tax. Spouses are treated as one person.^[6] For decades the statute had no regulations. In August 2018, proposed regulations issued with the Section 199A guidance would have presumed a tax avoidance purpose whenever separate trusts produced a significant income tax benefit. The final regulation, Treas. Reg. § 1.643(f)-1, was published in February 2019 without that presumption. It essentially restates the statute and applies to taxable years ending after August 16, 2018.^{[24, 25, 3]}

The IRS treats the area as sensitive. Since 2021 its annual no-ruling revenue procedure has listed whether two or more trusts will be treated as one under Section 643(f) as a question on which it will not issue a letter ruling.^{[26, 8]} The current list, Rev. Proc. 2026-3, goes further: it places ING trusts, and the question whether a corporation meets the Section 1202(e) active business requirement, among the areas under study on which rulings will not be issued.^[8] A family cannot obtain an advance ruling that the trusts in a multi-trust QSBS plan will be respected as separate. The plan has to stand on its design: distinct trusts, distinct beneficiaries, and real purposes beyond tax.^[3]

IRS administrative guidance

• Private letter rulings. Beyond the ING rulings, PLRs such as 201436001 and 201717010 address which businesses are "qualified trades or businesses," a corporate-level question rather than a trust question.^[27] In PLR 202244004 (released November 4, 2022), the IRS granted an extension of time to make a late Section 1045 rollover election. Section 1045 lets a taxpayer who sells QSBS held more than six months defer gain by reinvesting in other QSBS within 60 days, and because the cap is per issuer, reinvesting in more than one company can lead to more than one cap.^{[28, 29, 30]}
• Chief Counsel advice. In AM 2023-006, the Office of Chief Counsel rejected a marketed non-grantor trust arrangement that claimed to avoid tax by allocating gains to corpus. The memorandum does not involve Section 1202, but it shows the attention the IRS is paying to promoted trust structures.^[31] Commentators warn that an expanded QSBS benefit may attract the same kind of overpromotion the employee retention credit did.^[32]
• Section 1202(k). The statute directs Treasury to issue regulations to prevent avoidance of its purposes "through split-ups, shell corporations, partnerships, or otherwise." It is the authority most often cited for any future anti-stacking rule.^{[1, 33]}

What Treasury said in 2026

On May 20, 2026, Kenneth Kies, Treasury's assistant secretary for tax policy and acting IRS chief counsel, told a tax seminar in Washington, "Let me just warn you: We don't like stacking," echoing remarks by Treasury attorney-adviser Evan Adams on May 9. Reports describe the concern as arrangements that go beyond one trust per family member.^{[34, 35]} As of September 17, 2026, no notice, proposed regulation, or ruling has been released. Our companion article, QSBS trust stacking under Treasury scrutiny, tracks the developments and what they mean for existing trusts.

In summary, the law permits stacking: each individual donee or non-grantor trust has its own cap. But the IRS will not bless a plan in advance, and it has the tools to challenge trusts that are artificial, duplicative, or late.^{[6, 3]}

Judicial cases on QSBS and trust planning

Few cases interpret Section 1202, and none to date squarely addresses a contested multi-trust stacking arrangement. Several decisions guide the related issues: what qualifies, who bears the burden of proof, when a gift comes too late, and how states treat the gain.

• Owen v. Commissioner, T.C. Memo. 2012-21. An early Tax Court decision on the "qualified trade or business" definition, decided under the companion rollover provision, Section 1045. The IRS argued that an insurance-marketing company was a business whose principal asset was its owners' skill. The court disagreed, even while acknowledging that the owners' talent drove the company's success.^{[36, 37]} The taxpayer still lost the deferral, because the replacement company he funded held its assets almost entirely in cash and failed the active business requirement.^[38] Owen shows both that courts will read the qualification rules fairly in close cases and that every requirement must actually be met. It did not involve a gift or a trust.
• Estate of Hoensheid v. Commissioner, T.C. Memo. 2023-34. Not a QSBS case, but the most important recent authority on timing. A shareholder gave stock to a donor-advised fund two days before the company's sale closed. The Tax Court declined to apply a bright-line "binding obligation" test. It looked at the realities of the deal, found the sale practically certain by the date of the gift, and taxed the gain to the donor under the anticipatory assignment of income doctrine.^{[7, 39]} The lesson for founders hoping to stack is direct: a gift made once the sale is effectively locked in may simply be ignored, even though Section 1202(h) would otherwise let the donee tack the holding period.^[13]
• Ju v. United States, 170 Fed. Cl. 266 (2024). Described by commentators as the first reported decision squarely applying Section 1202.^[40] Dr. Ju claimed the exclusion in a refund suit and lost on part of his shares. The Court of Federal Claims held that the taxpayer bears the burden of proving the gross assets test was met through the date the stock was issued, found financial records from later years insufficient for that purpose, and rejected his argument that he had effectively held certain shares before the date his settlement agreement transferred them to him.^[41] For trust planning, the point is documentation. A trustee who sells gifted QSBS years later must be able to prove facts that date from the original issuance.
• Leto v. United States (D. Ariz. 2022). An Arizona case. The business began as an Arizona limited liability company that had elected S corporation status, and it was later reincorporated as a C corporation. The court agreed with the government that the owner received his C corporation shares in exchange for stock, which fails the original issuance requirement, because what counts as "stock" is a question of federal tax law and not Arizona law.^[42] Many Arizona business owners operate through LLCs. How and when a company converts to a C corporation decides whether there is any exclusion to stack.
• Aciu v. Director, Division of Taxation (N.J. Tax Ct. 2012). A New Jersey resident excluded half of her QSBS gain on her federal return and sought the same treatment on her state return. The Tax Court of New Jersey ruled for the Director of the Division of Taxation: New Jersey's gross income tax did not incorporate the Section 1202 exclusion.^{[43, 10]} New Jersey has since changed course and allows the exclusion for tax years beginning on or after January 1, 2026.^[10]

State conformity in 2026

Aciu still teaches the right lesson: the federal exclusion does not bind the states. As of September 2026, Alabama, California, Mississippi, and Pennsylvania tax QSBS gain in full. Illinois and Oregon require a full addback beginning in 2026, Maine denies the exclusion for stock acquired after July 4, 2025, and Hawaii allows only part of it.^[10] California's history is often misdescribed. In Cutler v. Franchise Tax Board, the Court of Appeal struck down California's own QSBS incentive because it favored companies with California property and payroll. California does not allow a QSBS exclusion today.^{[44, 45]} New York (since 2014) and California (since 2023) also tax the income of an ING trust to its grantor, which removes the state income tax benefit of that structure for their residents.^{[46, 47, 3]}

The cases reinforce four principles. (1) Plan early: a transfer made when a sale is practically certain invites assignment of income.^[7] (2) Prove everything: taxpayers and trusts carry the burden on every QSBS requirement.^[41] (3) Check the entity history: a flawed conversion can defeat original issuance.^[42] (4) Mind state law: a trust may save federal tax and still owe state tax.^[10] To these, add the unresolved one: if multiple trusts look like clones created only to multiply exclusions, the IRS could seek to combine them under Section 643(f), although no reported case has yet applied that section to a QSBS stack.

Commentary in legal journals and tax publications

Tax practitioners and academics have analyzed QSBS trust strategies closely, especially as the exclusion grew in value after the 100 percent exclusion arrived in 2010 and the corporate rate fell in 2017.^[3] The most useful pieces agree on the technique and differ mainly on how far it can be pushed.

• The Tax Adviser, "Qualified small business stock: Gray areas in estate planning" (Lederman and Casteel, April 2024). The article confirms that stacking is accomplished by gifting QSBS to family members and to irrevocable non-grantor trusts, each eligible for its own exclusion, and it urges early gifts, when values are low and little gift tax exemption is used. On "how many trusts are too many," it finds no bright line and treats Section 643(f) as the key constraint. Its practical advice: one trust per beneficiary, perhaps one additional pot trust for the group, documented non-tax purposes, different trustees, and distribution patterns that actually differ. It also reviews ING trusts and charitable remainder trusts as stacking vehicles, notes that New York and California tax ING income to the grantor, and flags that the treatment of excluded gain inside a charitable remainder trust's tier system is unclear.^[3]
• Tax Stringer (NYSSCPA), "Estate Planning for Founders and Investors in Venture-backed Companies: Transfers of Qualified Small Business Stock by Gift" (Arlein, May 2020). A detailed treatment of Section 1202(h). It explains why a gift to a grantor trust is not a transfer for Section 1202 purposes under Rev. Rul. 85-13, why "gift" for income tax purposes is not the same as a completed gift for gift tax purposes, and how outright gifts, completed gifts to non-grantor trusts, ING trusts, GRAT remainders, and charitable remainder trusts each fit the statute.^[11]
• Tax Notes Federal, "Stacking Qualified Small Business Stock: New Guidance on Anticipatory Assignment" (Karachale and Osheroff, July 24, 2023). The authors use Estate of Hoensheid to analyze when a pre-sale gift of QSBS will be recharacterized. Their recommendation is that founders not wait until the eleventh hour. Shares should move to trusts or family members well before term sheets harden into purchase agreements.^[13]
• Tax Notes Federal, "Fixing the QSBS Stacking Problem" (Polsky and Yale, September 7, 2026). Two tax professors who are critics of Section 1202 urge Treasury to respond to stacking short of new legislation. The article is a useful map of where regulators may aim.^[33]
• Packing and Section 1045. Discussions of stacking often travel with "packing." Because the dollar cap is per issuer, an entrepreneur with three $10 million companies has three caps, and a Section 1045 rollover into more than one replacement company can have a similar effect.^{[28, 30]} Because the alternative cap is ten times basis, measured when the stock was issued and ignoring later additions, holders of high-basis shares plan carefully which shares to sell in which year.^{[1, 14]}

The bottom line from the literature is that QSBS offers powerful opportunities and carries traps for the unwary. Publications stress coordination among advisers and careful compliance, and they warn that QSBS could become "a minefield if misused or overpromoted."^[32]

CLE materials and conference insights (ABA, ALI-CLE, estate planning conferences)

QSBS planning has been a regular topic at continuing legal education programs, including the Heckerling Institute on Estate Planning. These forums share cutting-edge strategies and are candid about risk.

• Heckerling Institute 2019, "Qualified Small Business Stock: The Quest for Quantum Exclusions" (Lee, Comeau, Kwon, and Long). The materials catalogue the potential holders of a separate per-issuer cap (an individual, a non-grantor trust, an ING trust, a pot trust that later divides into separate trusts) and chart how QSBS status carries over on different transfers. They also discuss what happens when a grantor trust stops being one. At the grantor's death, a formerly revocable trust becomes a separate taxpayer, and a transfer at death keeps QSBS status under Section 1202(h), which raises real planning questions in trust administration.^{[48, 1]}
• ACTEC Trust and Estate Talk, "Don't Guess and Make a Mess with QSBS" (Miller, October 2021). ACTEC Fellow Justin Miller explains the fundamentals in plain language and strongly favors non-grantor trusts for QSBS. His example is a founder who creates three non-grantor trusts for three children, giving the family four exclusions, with the trusts sited in a state that does not tax them. He also warns about the multiple trust rule: if the trusts "start to look too similar," Section 643(f) may treat them as one.^[12]
• The recurring CLE advice. Divide family holdings among trusts early, and avoid cookie-cutter trusts. Five identical trusts created the same day for the same beneficiary, each funded with QSBS, is the fact pattern Section 643(f) describes. Speakers recommend different beneficiaries, different terms, staggered funding, and stated non-tax purposes for each trust.^{[3, 26]}

These programs also discuss audit risk. Section 1202 claims were once rare. After years of large technology exits, they are not, and practitioners expect more questions about the gross assets test, the active business requirement, and returns on which several related trusts all exclude gain from the same sale.^{[3, 41]}

Practitioner white papers and planning guides

Law firms, accounting firms, and wealth advisers have published many client guides on using trusts with Section 1202. The better ones combine the rules with field experience.

• Firm memos on stacking. A widely read series from FBT Gibbons explains that a gift of QSBS to a non-grantor trust is a transfer to a separate taxpayer, that a transfer to a disregarded entity or a grantor trust is not, and that the donee tacks the donor's holding period. It recommends gifting when value is low and well before a sale.^[14]
• Risk mitigation under Section 643(f). Practitioner guides recommend separate beneficiaries for each trust, sometimes one discretionary "spray" or pot trust for a class of beneficiaries, and care not to have each spouse create a mirror-image trust for the same child, since spouses count as one grantor.^{[6, 3]}
• State tax and residency planning. Trust situs can decide whether a trust's gain is taxed by a state. California, for example, taxes a non-grantor trust based on the residence of its trustees and its noncontingent beneficiaries, and a separate rule can tax a resident beneficiary on accumulated income when it is later distributed.^{[49, 50]} A founder with California ties needs that analysis before relying on a stacked exclusion. See the Arizona angle below.
• Combining trust and non-trust strategies. A BDO analysis notes that non-grantor trusts can add exclusion limits while grantor trusts have their own benefits, and it recommends a break-even analysis of the two.^[51] The main grantor trust benefit is that the grantor's payment of the trust's income tax is not treated as a further gift.^[52] Some planners use a grantor trust first and end grantor status before a sale, which is sophisticated, unblessed by the IRS, and sensitive to timing.^[48]
• Audit and compliance. Guides recommend an audit file: the corporate charter, stock purchase or subscription documents proving original issuance, financial statements or a gross assets calculation as of issuance, records of the company's activities, any company QSBS representation letter, and the gift documents, appraisals, and trust instruments. Each trust should keep its own accounts and records so that its independence is visible.^{[41, 40]}

Common trust-based QSBS strategies

Each technique has advantages and costs, and practitioners often layer them. A founder might gift some shares outright, some to a non-grantor dynasty trust, and some to a charitable vehicle. The consistent thread is that non-grantor trusts are the linchpin of stacking for family members.^[12]

How QSBS stacking fits the rest of your estate plan

Stacking is an income tax technique carried out with estate planning tools, and it has to work with everything else in the plan. These are the intersections we see most often among the clients we serve.

• Your revocable living trust. Shares held in a revocable trust are treated as yours, so the trust adds no cap. At death the shares keep their QSBS status under Section 1202(h), but they also generally receive a basis step-up, so the built-in gain largely disappears either way.^{[1, 56]} Our guide to revocable trusts, estate tax, and basis explains the step-up.
• SLATs. A SLAT is usually a grantor trust and generally shares your cap. It may still be the right home for some founder stock for estate tax reasons. See our SLAT planning guide.
• Dynasty trusts. A non-grantor dynasty trust can do two jobs with one gift: claim its own exclusion at sale and keep the proceeds outside the transfer tax system for generations. See dynasty trusts and generational planning.
• Children's trusts. One trust per child is both the most common stacking pattern and the pattern officials have signaled is least concerning.^[34] Our article on children's trusts for lifetime planning covers the design choices.
• BDITs and BDOTs. A trust taxed to its beneficiary under Section 678 is, for income tax purposes, the beneficiary's own, so it generally shares the beneficiary's cap and does not add one.^[57] Compare the structures in BDITs versus BDOTs.
• Family limited partnerships and LLCs. This is a trap. A contribution of QSBS to a partnership or multi-member LLC in exchange for an interest is not among the transfers Section 1202(h) protects, and leading commentary warns that it destroys the stock's qualified status.^{[1, 14]} Founder stock usually should stay out of the family partnership.
• Life insurance. Pre-exit founder wealth is illiquid. An irrevocable life insurance trust can supply cash for estate tax or buy-sell obligations without forcing a sale of shares.
• Existing trusts that need work. Where an older trust's terms undermine non-grantor status or independence, trust modification or decanting may help, if done for sound reasons and well before any sale.
• The people around the plan. Executives with equity compensation, family offices, multi-generational families, athletes and public figures who invest in early-stage companies, and founders now planning in retirement all face versions of the same question: who should own the shares on the day of sale.

The Arizona angle: Scottsdale and Paradise Valley founders

Arizona is a favorable place to hold QSBS. Arizona conforms to the Internal Revenue Code as of a fixed date, and H.B. 4168, signed June 13, 2026, moved that date to January 1, 2026 and adopted the 2025 federal changes, including those with retroactive effective dates.^{[9, 58]} For most Arizona residents, gain excluded under Section 1202 on the federal return is excluded on the Arizona return as well. Confirm the result for your year of sale with your CPA. Arizona also has no estate, inheritance, or gift tax.^[59]

Three Arizona points matter in trust design:

• When Arizona taxes a trust. A trust is an Arizona resident trust if at least one fiduciary is an Arizona resident. Where a corporate fiduciary engaged in interstate trust administration is the sole fiduciary, or serves with a nonresident, the trust is a resident trust only if the corporate fiduciary administers it in Arizona.^[60] Because Arizona follows Section 1202, residency matters less for the excluded gain than for everything the trust earns afterward.
• No self-settled asset protection trusts. Under Arizona law a settlor's creditors can reach the maximum amount a trustee could distribute to the settlor.^[53] ING trusts depend on the opposite rule, so Arizona residents who use them form them in states such as Nevada, Delaware, or South Dakota.
• Community property. Arizona is a community property state. How founder shares are titled and characterized between spouses affects who the donor is, how the gift is reported, and how the one-grantor rule for spouses applies under Section 643(f).^[6]

Where Arizona families get caught is across the state line. California does not follow Section 1202 and can tax a non-grantor trust through a California trustee or a California beneficiary.^{[45, 49]} Families who moved to Paradise Valley or North Scottsdale from California, who name a sibling in California as trustee, or whose adult children live there should review trust situs before relying on a stacked exclusion. And as Leto shows, Arizona companies that began as LLCs need a careful look at how they became C corporations.^[42]

We meet founders and their advisers at our Scottsdale office in the Airpark, serve families in Carefree and across the north Valley, and work by secure video with clients elsewhere in Arizona. All of our locations and meeting options are listed on one page.

A founder's QSBS stacking checklist

1. Confirm the stock qualifies. Original issuance, C corporation status, the gross assets ceiling at issuance, and the active business test throughout the holding period. If the company was ever an LLC or S corporation, review the conversion.^{[1, 42]}
2. Identify which track each block is on. Shares acquired on or before July 4, 2025 and shares acquired after it carry different caps and holding periods.^[1]
3. Model both caps for each holder. Compare the dollar cap with ten times basis, and decide how many separate taxpayers the expected gain actually supports.
4. Start with the family, not the tax. Decide who should benefit and why. Design one trust for each real purpose.
5. Draft true non-grantor trusts. Independent trustees, no spouse as beneficiary unless carefully limited, and no retained powers that create grantor trust status.^{[5, 22]}
6. Appraise and transfer early. Obtain a qualified appraisal as of the gift date and complete gifts long before any letter of intent.^[7]
7. Report the gifts. File Form 709 with adequate disclosure so the statute of limitations on the gift's value begins to run.^{[61, 62]}
8. Run each trust as its own trust. Separate accounts, separate records, separate trustee decisions, and a Form 1041 for each.
9. Build the audit file now. Collect the issuance documents, gross assets support, and company QSBS representations while the people who can provide them are still at the company.^[41]
10. Coordinate the team. Your corporate counsel, CPA, and wealth adviser each hold a piece of this. We work alongside CPAs and financial advisors on exactly this kind of plan.

Conclusion

Planning with qualified small business stock can reduce or eliminate capital gains tax for entrepreneurs and investors, and trusts can multiply the savings. Grantor and non-grantor trusts play very different roles. A grantor trust keeps the stock's tax attributes with the grantor: no new Section 1202 cap, but real estate tax benefits. A non-grantor trust is a separate taxpayer eligible for its own exclusion.^{[4, 1]} Stacking exclusions through gifts to multiple non-grantor trusts is well established in practice and rests on the statute's text: a per-taxpayer cap, an express rule preserving QSBS status for gifts, and no rule combining donor and donee.^[1]

The area sits where tax policy and anti-abuse enforcement meet. Avoid carbon-copy trusts with no purpose other than tax, or Section 643(f) may be invoked.^[6] Respect the assignment of income doctrine, which means transfers cannot wait for the eve of a sale.^[7] The safest path is early, proactive planning: well-differentiated trusts created years before an exit, with every QSBS requirement documented.^[41] Done that way, a family can legitimately turn one $10 million or $15 million exclusion into several.

Finally, stay current. Treasury has said guidance is coming, Congress changed the statute in 2025, and states keep moving.^{[34, 10]} With careful structuring and attention to the economic reality of each trust, QSBS stacking with non-grantor trusts remains one of the most valuable tools available to a successful founder's family.

How Boland Law Group approaches QSBS planning

Boland Law Group is a Scottsdale estate planning and tax firm with a deliberately narrow practice. Both of our attorneys, Grant M. Boland and Robert W. Boland, Jr., hold LL.M. degrees, one in taxation and one in estate planning, and both are admitted to the United States Tax Court. The firm that designs the plan also handles tax controversy and litigation, and has served Arizona families for more than fifty years. That matters for stacking, because the question Treasury is now asking is the one a tax litigator asks first: how would this be defended?

Our QSBS planning for founders starts with whether the stock qualifies, then the family's goals, then the trusts. Companies that want the same judgment applied to the business itself use our outside general counsel service. You can read more about the firm or browse all of our insights.
